IMPROVEMENT IN REVOLVING FIRE-ARMS.

Specification forming part of Letters Patent No. 55,743, dated Juno 19, 1866.

To all whom it mayconcem:

Be it known that I, WILLIAM TIBBALS, of' South Coventry, in the county otTolland and State of Connecticut, have invented certain new and useful Improvements in Cylinders for Fire-Arms; and I do hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, making part ofthis specilication, and to the letters ot' reference marked tl. -reon, like letters indicatinglike parts wherever they occur.

fo enable others skilled inthe art to construct and use the invention, I will proceed to describe it.

Figure l is a front-end view. Fig. 2, a side View, Fig. 5, a rear-end view, Fig. 4, a lon gitudinalsect-ion; and Figs. 5, 6, and 7, views ot' the cartridges to be used in my improved cylinder.

My invention relates to that class otl tirearms in which a revolving cylinderis used g and it consists in a peculiar manner ot' forming the chambers therein, to adaptit to the use ot' me tallic cartridge-cases, in which a pin is usedto ignite the charge.

C represents a cylinder having the chambers bored in it, but not extending entirely through, as shown clearly in Fig. 4. Vhcn itisdesired to use the cartridgel'iavinga long pin projecting from the side, as shown in Fig. 5, a slot, b, as shown in Fig. 2, is cut m the side ofthe barrel through to the chamber to permit the pin e to slide in as the cartridge is inserted from the frontend of' the cylinder. When this form is used the charge is ignited by having the hammer strike upon the projecting end of the pin, as is now done in arms using that style of cartridge.

To obviate the necessity of weakening' the cylinder by cutting the slot b in it, I propose to shorten the stem or pin c, as shown in Fig. 6, and simply cut a groove, n, in one side ot' the barrel or chamber of sutiicient depth to permit the pin e to slidetherein, and thus allow the cartridge a to be inserted, as shown in Figs. l and 4. At the rear end ot' the chamber, and directly over the pin e, a hole, 0, is made through the side ot' the cylinder, as shown in Fig. 4, for the point of the hammer to strike through and hit the pin c.

there the pin c is inserted at the eud ot' the cartridge, as shown in Fig. 7, Isimply provide a hole, oit, tor the pin c to rest in, as shown in Figs. 3 and 4, the pin either projecting through the rear ot'the cylinder or simply resting in the hole, and there struck by the point ot' the hammer.

'fVllen this style ot' cartridge is used, it can be shoved ont, at'ter it is exploded, by inserting a small rod through the hole oit from the rear; and when the style otl cartridge shown in Fig. o' is used asimilar hole, o', as shown in Figs. and 4. is made at the rear end ot' the chamber, for the purpose ot' shoving out the cartridge-case by theI insertion ot' a small rod, in a similar manner.

Either ot' these t'orms may be used, as preferred; but the last is obviously the best, as the barrel is not weakened, as in the others, by the cutting therein ot the slot or groove.

Having thus described my invention, what I claim is- Constructing the chamber of tire-arms with the groove or slot in its side for the reception of the pin-cartridge, substantially as herein shown and described.
